Product details

Overview

CLVTH16240IDGGREP from Texas Instruments is a 16-bit inverting 3-state buffer/driver designed for 3.3-V V_CC operation with 5-V tolerant inputs and outputs, supporting mixed-mode signal interfacing between 3.3-V logic and legacy 5-V systems. It features four independent 4-bit sections, active-low output-enable (OE) control per section, bus-hold on all data inputs, and I_off/power-up 3-state for hot-insertion. Typical propagation delay is 2.2 ns at V_CC = 3.3 V, and it operates across −40°C to 85°C in TSSOP-48 packaging.

For engineers reviewing the CLVTH16240IDGGREP datasheet, CLVTH16240IDGGREP pinout, CLVTH16240IDGGREP application, or CLVTH16240IDGGREP equivalent, key selection considerations include its 3.3-V core with 5-V I/O tolerance, symmetrical OE architecture, bus-hold elimination of external pull resistors, distributed power/ground pins for noise reduction, and qualification for enhanced reliability in industrial environments.

Technical Context

This device implements a flow-through pin architecture optimized for PCB layout density and signal integrity, with separate OE inputs per 4-bit group enabling granular bus control. Its ABT (Advanced BiCMOS Technology) process delivers low static power dissipation while maintaining TTL-compatible drive strength and input thresholds.

The CLVTH16240IDGGREP integrates I_off circuitry that disables outputs when V_CC = 0, preventing backflow current during hot insertion, and power-up 3-state ensures outputs remain high-impedance until V_CC exceeds 1.5 V. Bus-hold current ranges from ±75 µA at V_CC = 3 V, actively retaining valid logic states on floating inputs without external components.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVTH16240DGGR	Same die, identical electrical specs, but commercial-grade (0°C to 70°C) and non-EP; RoHS-compliant but no enhanced DMS or qualification pedigree.	Not qualified for extended temperature or high-reliability industrial use; lacks HAST, temperature cycle, and mold compound life testing.	Select CLVTH16240IDGGREP when operating beyond 70°C or requiring TI's enhanced product-change notification and controlled baseline manufacturing.
SN74LVT16240DGGR	Non-Bus-Hold variant; requires external pullup/pulldown resistors on all inputs; slightly higher ICC (0.35 mA vs. 0.19 mA) in disabled state.	Lacks bus-hold, increasing BOM cost and PCB area; unsuitable for systems with intermittent or undefined input states.	Choose CLVTH16240IDGGREP where floating inputs are unavoidable and system-level reliability must be maintained without external components.

Compared with SN74LVTH16240DGGR and SN74LVT16240DGGR, the CLVTH16240IDGGREP provides guaranteed extended-temperature operation, enhanced reliability qualification, and integrated bus-hold-enabling simpler, more robust designs in industrial and infrastructure applications without layout or component compromises.

FAQ

What is the operating temperature range for CLVTH16240IDGGREP?

The CLVTH16240IDGGREP is specified for operation from −40°C to +85°C ambient temperature. This extended industrial temperature range is validated through JEDEC-qualified testing including temperature cycling and biased 85/85, making it suitable for deployment in demanding environments such as factory automation controllers and outdoor communications equipment where thermal stability is critical. The CLVTH16240IDGGREP maintains full electrical compliance across this entire range.

Does CLVTH16240IDGGREP support hot-plug insertion?

Yes, the CLVTH16240IDGGREP supports hot-insertion via dual protection mechanisms: I_off circuitry disables outputs when V_CC = 0 V to prevent damaging current backflow, and power-up 3-state holds all outputs in high-impedance until V_CC exceeds 1.5 V. These features are explicitly verified per TI's enhanced product qualification and allow safe live insertion into powered backplanes without risk of bus contention or component damage. The CLVTH16240IDGGREP implements both functions natively without external circuitry.

How does bus-hold functionality work on CLVTH16240IDGGREP?

The CLVTH16240IDGGREP integrates active bus-hold circuitry on all 16 data inputs (1A1–4A4), which applies ±75 µA of holding current to retain the last-valid logic state when inputs float. This eliminates the need for external 10-kΩ pullup or pulldown resistors, reducing BOM cost and PCB area. Bus-hold operates across the full V_CC range (2.7 V to 3.6 V) and is confirmed in TI's SCBS777 datasheet under electrical characteristics. The CLVTH16240IDGGREP's bus-hold ensures deterministic behavior in systems with intermittent signal sources or unconnected test points.

What package type and lead finish does CLVTH16240IDGGREP use?

The CLVTH16240IDGGREP is packaged in a 48-pin TSSOP (Thin Shrink Small Outline Package) with drawing code DGG, measuring 12.5 mm × 6.1 mm with 0.5-mm lead pitch. Its lead finish is CU NIPDAU (copper with nickel-palladium-gold), compliant with RoHS and halogen-free standards (Green: no Sb/Br). Moisture sensitivity level is rated JEDEC Level-1 with unlimited floor life at ≤30°C/60% RH. This package is optimized for automated SMT assembly and thermal performance in dense industrial PCB layouts. The CLVTH16240IDGGREP's DGG package is documented in TI's official packaging addendum dated 18-Sep-2008.

Can CLVTH16240IDGGREP interface directly with 5-V logic systems?

Yes, the CLVTH16240IDGGREP supports direct interfacing with 5-V logic systems: its inputs tolerate up to 7 V (exceeding 5-V TTL high-level thresholds), and its outputs drive 5-V loads while powered from a 3.3-V V_CC. The device meets VIH ≥ 2.0 V and VIL ≤ 0.8 V at V_CC = 3.3 V, ensuring reliable recognition of 5-V input signals. Output VOH reaches 2.4 V at I_OH = −8 mA, satisfying TTL high-level requirements. This mixed-mode capability is intrinsic to the CLVTH16240IDGGREP's ABT process and is fully characterized in the recommended operating conditions table of SCBS777.
